a domino is a rectangular tile composed of two squares. an integer is represented on both squares, and each integer 0-9 is paired with every integer 0-9 exactly once to form a complete set. a double is a domino that has the same integer on both of its squares. what is the probability that a domino randomly selected from a set will be a double? express your answer as a common fraction.
The probability that a domino randomly selected from a set will be a double = 2 / 11
what is probability?
A thing's probability indicates how probable it is to happen. When we are uncertain about the result of a given event, we can talk about the probabilities of several outcomes—how likely they are. Statistics refers to the study of events that have a probability component.
When 'n' is the largest integer in the set, the total number of dominoes in the set is given by the following formula:
(n + 1) (n + 2) / 2
This means that (9 + 1) (9 + 2) / 2 =
(10)(11)/ 2 =
110/2 =55
10 of these dominoes will be "doubles"
So....the probability that a domino randomly selected from a set will be a double = 10 / 55 = 2 / 11

The required rate are the people moving apart 3 minutes after the woman starts walking is 2.36 ft/S.
Explain the rate of change of distance.The rate of change of distance is speed ( not uprooting). Similar distance in different headings is alluded to as a similar distance.
According to question:Let x and y be the distance of the man and woman respectively.
We have,
dx/dt = 2 ft/s, dy/dt = 1 ft/s
Then, x = 2×6×60 = 720 ft
y = 1×5×60 = 300 ft
And in triangle which make by the locus of man and woman.
(x +y)^2 + (800)^2 = z^2
z = √(1020)^2+(800)^2
z = 1296.3 ft
So, people are 1296.3 ft apart,
Rate change
[tex]\frac{d}{dt}[/tex](x+y)^2 = [tex]\frac{d}{dt}[/tex]z^2
2(x+y)(dx/dt+dy/dt) = (2z)dz/dt
(720+300)+(2+1) = (1296.3)dz/dt

Given that about 25% of the mammalian genome is associated with genes, including introns and regulatory sequence, what would be the approximate average length of dna per gene if the genome contained 20,000 genes?
The average length of DNA per gene would be 40,000 base pairs if the genome had 20,000 genes.
Average gene length: just 2.5% of the human genome codes for proteins. The remaining 97.5% are introns. The male nuclear diploid genome measures 205.00 centimeters (cm), is 6.27 Gigabase pairs (Gbp), and weighs 6.41 picograms (pg). 208.23 cm, 6.51 pg, and 6.37 Gbp are the female measurements. "The overall number of base pairs, which is the length of DNA per gene, will be roughly twice the number of genes present in the genome, in this example 40,000, for a 25% mammalian genome with 20,000 genes".
A DNA region from which an mRNA is transcribed is the de facto definition of a "gene" in mammalian genome annotation. Because one cannot deduce function from a genome sequence alone, the correct functional genetic definition of a gene—a segment of DNA that can complement a mutant phenotype—is lost.

The employee estimates that the entire family will fill 6 prescriptions per month, totaling $850. The monthly premium for the plan is $55, with 90% coverage for the first $600 in prescription costs, then 80% coverage for all prescription costs over $600. What is the total out-of-pocket
expense for one month?
A. $685
B $795
C $110
D $165
The monthly prescription of $850, and the 90% coverage for the first $600 and 80% coverage for the prescriptions over $600 indicates that the total out-of-pocket by the family for one month is $110.
The correct option is option C. $110
What is an out-of-pocket expense?An out-of-pocket expense is an health expense incurred by an insured person, for which the insured person is not reimbursed.
The monthly premium for the family's health insurance plan = $55
The coverage offered by the health insurance for the first $600 = 90%
The coverage for prescription above $600 = 80%
The expected number of prescriptions by the family per month = 6
The total cost of the family's monthly prescription = $850
Therefore, the out-of-pocket expense by the family for one month are;
Out-of-pocket prescription for the first $600 = $600 - 90% × $600 = $60
Amount of prescription over $600 = $850 - $600 = $250
Out-of-pocket for prescription above $600 = $250 - 80% × $250 = $50
The total out-of-pocket expense for one month = $60 + $50 = $110The correct option is therefore, option C $110

the robinson family and the wong family each used their sprinklers last summer. the water output rate for the robinson family's sprinkler was per hour. the water output rate for the wong family's sprinkler was per hour. the families used their sprinklers for a combined total of hours, resulting in a total water output of . how long was each sprinkler used?
Robinson's time is 25 minutes and Wrong' time is 40 minutes.
Equation of Time:
x + y = 65 -------------------------- (1)
Total usage amount:
15x + 35y = 1775 -----------------------------(2)
There are several ways to answer this question. I will teach we how to create two equations from the given information. First we need to set some variables (or unknowns). we need to set up a sprinkler time variable for each household. Let's call the time of the Robinson family "x" and the time of the Wrong family "y". The total time used was 65, so the first formula is x + y = 65 ( Robinson's time plus Wrong's time gives total time).
Now,
We use the other hourly water information (remember we already have time variables for each family, x and y). We can set the following equation as 15x + 35y = 1775 (15 liters x the amount of time the Robinson's use water plus 35 liters x the amount of time the use water gives equal to total usage).
Now,
We can solve for one of the variables (x or y). It doesn't matter which one we start with. Also, it doesn't matter which formula you start with. I used
x + y=65 . On the other hand, subtracting x gives y = 65 - x.
Now,
Replace y in the other formula. 15x + 35y = 1775 turns into
15x + 35(65-x) = 1775.
Distribute 35 to each term in brackets. By isolating the x variable: x=25
Recall that x means how long the Robinson's have been using sprinklers.
Now,
We can plug x into the other equation: 25 + y = 65
Therefore,
Subtract 25 on the other side to isolate y: y= 40

What is the combination?
A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The number of k-combinations for a set with n components
The word is the mailbox.
So it contains 7 words and the total number of arrangements will be 7! = 5040.

Answer: Yes
Step-by-step explanation:
There are 676 sets of unique first and last initials, there being 26 for the first and 26 for the last. With 700 people, there are not enough unique combinations for everyone to be different. Therefore, in a group of 700 people, there will always be two who have a matching first and last initial.
What is the meaning of the term splitting and why is it used?
The term splitting is one of the methods used in factoring the quadratic expression.
We know that the general form of quadratic equation is ax² + bx + c = 0
The term splitting is one of the methods used in factoring the quadratic equation. When we can not square the first and the last term of the quadratic expression then we can use the method of splitting of the middle term. In this method we have to rewrite the middle term of the quadratic expression as the sum or difference of the two terms (the first and the last term).
For example, to factor a quadratic expression 4x² + 8x - 5
first find the product of the first and last term: 4 x (-5) = -20
Now, find the factors of -20 in such way that addition or subtraction of that factors is the middle term (8x) (Splitting of middle term):
10 x (-2) = -20 and 10 - 2 = 8
Now we write the quadratic expression using the sum of the two new factors, including the proper signs.
4x² + 10x - 2x - 5
Now,factor each pair by finding common factors.
2x( 2x + 5) - 1(2x + 5)
Now, factor out the common binomials.
(2x - 1) ( 2x + 5)
Therefore, the quadratic factorization uses splitting of middle term wtere the middle term of quadratic expresseion is splitted in to two factors.
